摘　　要：讨论了深空软着陆的一般方式和过程,描述了软着陆制导控制的总体方案。以燃耗最省为性能指标,分析推导了一种用于软着陆动力下降段的多项式制导控制律。以安全可靠为基本要求,分析推导了用于最终着陆段的重力转弯着陆方法。最后通过仿真证明了此模型是合理可行的,且方法简单。In this paper,the general way and the process of deep space soft landing is discussed,and the overall scheme of the guidance control in soft landing is described.With minimal fuel for performance index analysis,a kind of soft landing power decline of polynomial guidance law is obtained.With the basic requirements for safety and reliability,analysis is used to segment the gravity of the final landing turn landed method.Finally,the simulation results proved that the model is reasonable,feasible and simpler.
